Given:
The initial mass of an element is 800 grams.
Decay rate = 8.2% per day
Number of days = 15
To find:
The remaining element after 15 days.
Solution:
The exponential decay model is
Where, a is the initial value r is the rate of interest and t is time period.
Putting in the above formula, we get
Therefore, the mass of the remaining element is 221.7 grams.
Hello,
which principle?
f(x)=-x²+2x
==>f'(x)= -2x+2
You mean maybe this
f(x+h)=-(x+h)²+2(x+h)= -(x²+2hx+h²)+2x+2h
f(x)=-x²+2x
